A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

TRANSCENDING THE TRAJECTORY OF CYCLICAL IMPASSE: IN SEARCH OF A NEW BEGINNING IN ESIABA IROBI’S NWOKEDI [PDF]

open access: yesDiversitate si Identitate Culturala in Europa, 2013
Arguably, Nigeria’s transition from the military regime to the democratic rule in 1999 only marginally altered its political context dramatically. Nevertheless, corruption and mismanagement of her economic potential portentously remain her abiding ...

Rethinking the role of top-down attention in vision: effects attributable to a lossy representation in peripheral vision

open access: yesFrontiers in Psychology, 2012
Common wisdom in the field of human vision suggests that top-down selective attention is required in order to bind features into objects. Without selective attention, presumably we are unable even to distinguish such simple stimuli as a rotated T vs.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

open access: yesMolecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

DCU search runs at MediaEval 2012: search and hyperlinking task [PDF]

open access: yes, 2012
We describe the runs for our participation in the Search sub-task of the Search and Hyperlinking Task at MediaEval 2012. Our runs are designed to form a retrieval baseline by using time-based segmentation of audio transcripts incorporating pause ...

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

open access: yesMolecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.
